  1. 6. Short-Packet Communications: Fundamental Performance and Key Enablers

    Författare :Johan Östman; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Rayleigh fading; Block-fading channels; Rician fading; variable-length stop-feedback; short-packet channel codes.; ultra-reliable low-latency;

    Sammanfattning : The paradigm shift from 4G to 5G communications, predicted to enable new use cases such as ultra-reliable low-latency communications (URLLC), will enforce a radical change in the design of communication systems. Unlike in 4G systems, where the main objective is to have a large transmission rate, in URLLC, as implied by its name, the objective is to enable transmissions with low latency and, simultaneously, very high reliability.

  3. 7. Innovationsmiljöer i bronsålderns samhälle och idévärld : kring ny teknologi och begravningsritual i Västergötland

    Författare :Eva Weiler; Umeå universitet; []
    Nyckelord :HUMANIORA; HUMANITIES; megaliths; bronze; moulds; technology; innovation; communication; distribution; ideology; personified symbols; two-dimensional pictures; burial rites; Fornlämningar; Gravar; Bronsarbeten; Gravskick-- Sverige -- Västergötland; Sverige-- Västergötland -- Småland -- Skåne -- Halland;

    Sammanfattning : The aim of this thesis is to elucidate on the factors that lay behind general occurrences in society that diversely develop according to the variance in social and cultural backgrounds. The thesis encompasses the period between 2000-500 BC and concentrates on the effects of the introduction of a new technology (metal working) and new burial rites on the society in SW Sweden (Västergötland).

  4. 8. Neurocognitive Foundations of Child and Adult Number Processing : Neural Correlates and Functional Circuits Across Typical Development

    Författare :Mikael Skagenholt; Ulf Träff; Kenny Skagerlund; Karin Kucian; Linköpings universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Numerical cognition; fMRI; Triple code model; Cardinality; Ordinality; Functional connectivity; Development; Numerisk kognition; fMRI; Kardinalitet; Ordinalitet; Utveckling;

    Sammanfattning : The ability to mentally represent the exact numerosity of up to four perceived objects, as well as approximately estimating differences in numerical magnitude, appears to constitute a core-cognitive number sense. Symbolic representations of number (e.g. LÄS MER

  5. 9. The Ecstasy of Tragedy : An Ethnography of Hospice

    Författare :Oscar Wandery; Christian Maravelias; Carl Cederström; David Knights; Stockholms universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Organizational culture; hospice care; health care; affect research; ecstatic rituals; cultural reproduction; Business Administration; företagsekonomi;

    Sammanfattning : Culture is a double-edged sword in organizational research. Certain researchers consider culture the key to understanding organizations while others see it as a pseudo-scientific and faddish term. LÄS MER

  7. 10. Partial Response and Faster-than-Nyquist Signaling

    Författare :Fredrik Rusek; Institutionen för elektro- och informationsteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Telecommunication engineering; Signalbehandling; Signal processing; Partial Response Signaling; Faster-than-Nyquist Signaling; Digital Communications; Coding Theory; Telekommunikationsteknik;

    Sammanfattning : Bandwidth efficiency is a key objective in the design of a digital communication system. Traditionally it is accomplished by increasing the constellation size of the signaling system. In this thesis alternative techniques are studied. Because the communication channel is continuous, so must the actual time signals be. LÄS MER
